DRIER AND STEAMER FOR 13113111.1112.'rninrczstl Application filedNovember 21, 1927'. Serial No. $234371.

Tubular knitted or woven fabrics, if made ot silk, libre, cotton orwool7 or mixtures of` these, are in most cases dyed, bleached or washed.`After the operations referred to the abric is put 1n an extractor toextract the liquid. Although the liquid is extracted to a considerableextent the fabric still remains moist and requires drying. Alter thefabric is dried it is necessary to subject it toa steaming process tomake it sott and to give the fabric the right linish.

My invention relates more particularly to drying means and to therelation ot the` drying means to a steaming device, the purpose in viewbeing to effect the drying and steam ing of the fabric in one operationand the eftesting of a saving in time and labor.

The nature of my invention and its distinguishing features `andadvantages will clearly appear as the description proceeds.

Reference is to be had to the accompanying drawings forming part otthisspecitication, it being understood that the drawings are merelyillustrative of one example of the invention. y i

I have shown in the illustrated example of y my invention the adaptationof the drying means constitutinof the present invention to a steamingassemblage forming part of the subject matter of an application forpatent tiled by me November 4, 1927 Serial No.

231,124.' In the steaming assemblage referred to a steam bowl 10 isprovided openY at` the top for theescape of the steam. Said bowl isclosed by asolid disc 11 having a central bore and a nipple 12`onsaiddisc which nipple extends into a steam pipe 13 mounted on a suitablebase 14 and supplied with steam through au inlet pipe 113.` The `pipe`lrisesftrom the d1sc"11 or bottom of the bowl 10 at the nipple .131 sothat the" steam "flowing from said nipple 12 will pass into` the pipe15` which isformed with aseriesof apertures he upperl endof the pipe 15is reduced las at 17 and ex-` ternally threaded to receivefthe bottom 18of` a steam dome or drum`19 which is screwedto 1G tor the escape ofthesteam.` 1

said reduced terminal "17.` f Steam dome 19 is filled with steam passinginto the samefroin pipe 15.

The bottom 18 oft the steam dome ondrum` 19 is spaced from the openvupper end of` the steam bowl 10 by an` outlet space 2() `thercbetweenfor the ample flow ot steam outwardly to contact with the tubular'fabric A, indicated in dot-and-dash lines, `as said 'labricis drawnupwardly overtlie bowl 10,

dome 19and overa stretcher'21.

The stretching frame 21 isfan `open trame thefsides ofvvhich risefromthe bottom bar 22 y A threaded #bolt 24 passes u through bottom barV 22`atthe `center and of said frame.

through a disc `25.011 the plug 119orming a closure at thetenter` at thetop ofthe dome 19.`

Screw bolts 27 1pass through disc 25 and into,"

the plug or block 119 as fully disclosedin my Vabovementionedapplication. Y i

1A stretching ring 30 is providedon'tlle` dome 19 `and removably heldseatedfupon washer 4L Forthe removable holdingof` collar 3() the same isformedwith notches 31 at its inneiI periphery` and onthe dome 19 are f ioutwardlyprojecting pins 32`fsot-hat the col-` lar may be passeddownwardly beneath the y horizontal planeet pins 32 and tbe collar thenf given a partial turn for the pins to hold said collar in place. Thecollar 41 rests upon the upwardlydirected annular llange 39 en dome 19and the bottom `18`is`clamped by screws 42:

between said `flange 39and ring `l0 on the under side o1. said "bottom`18. Drip pipe 35 leadsrfrom the bottom ofdome `19 into `steam bowl 10`t`direct to said bowl the Water of i condensationfrom the dome `19.Similarly `a drain pipe 36 leads fromlsteam bowl 10 to carry off thewater of condensation. The numeral 37 indicates {iange or collar on thesteam pipe 13 which is suitably secured to the solid bottom 11 of dome10.

The assemblage above described provides for the free flow of steam tothe fabric and in order that the space 20 forl the outflow of the steammay be Varied, I provide collars r washers34 on the reduced end 17 ofpipe 15, said collars being employed in suitable number according to thesize to be given to space 20. Y

With steam-dome 19 filled with steam the `said dome serves to dry tliefabric passing over thesame when drying isrequired. The steam escapingthrough the space does not actually wetthe fabric, and in some instanceswhen the fabric is moist. from too much steam the dome 19 has thedesired drying effect. lVheii vdrying is not desired the dome 19 isclosed against the entrance of steam by einvploying a plug in thereduced end 17. A plug 135 is also employed to close the lower end ofdrip pipe 35 when the steam dome 19 is closed against the entrance ofsteam in order to prevent steam passing into said `dome through pipe 35from the bowl 10. Y

In accordance with iny present invention the drying means includes acylindrical shell which surrounds the steam supply pipe 13 as well asthe drain pipe 36. An air inlet pipe 51 leads laterally into shell 50and is sup plied with air under pressure. Said shell 50 is closed by anysuitable means at the top and bottom, there being shown a plug formed ofhalf sections 52, see more particularly Figure G. The shell 50terminates at the top short of the bottom of the steam bowl 10, thepipes 13 and 36 extending beyond the upper closure elements 52 to aconnection with, said bowl `10. y Surroundingthe shell 50 at any desiredpoint in its height is a perforated drying drum 53, in which shell 50there are perforations 54 for theescape of heated air to the drum 53.The airescaping from the perforated druni into contact with "and passingthrough the fabric effects the drying ofthe fabric. The drying drum 53may rest on a fired collar 55 on the air tube or shell 50. At

the top of said drum 53 is a set screw A56 to bind the drum on the shell50 at any desired height. thereon that will permit air to pass' intodrum 53 from perforations 54. By loosening the screw 56 the drum 53 maybe slipped upwardly and entirely removed from the shell 5() after steambowl 10 and steam drum 19 have been removed from the upper end of thepipes 13, 36.

Vlfith the steam. bowl 10, steam `drum 19 and drying drum 53 removedfrom the assemblage, the fabric may beslipped downwardly a drying shellhaving an inlet for drying over the shell 50. In order to facilitate theplacingof the tubular fabric over` the pipes 13, 36 and shell 50, Iprovide,` as in Figures 7 and 8, a dome 57 depending from which is aplug 58 adapted to fit in the upper end of the steam pipe 13, as shownclearly ni Figure 3.

In the use of the above described device the fabric having been placedin posi tion, as in dicated in dot-and-dasli lines in Figures 2 and 3,any remaining moisture in the fabric will be driven off and the fabricmade dry bytlie drying air escaping from the perforations 5a of shell5t) and through the perforations in drum The drying will thus beeffected as the fabric drawn upward over the drum 53. As the fabricpasses from the upper end ofthe shell 50 it is drawn over the bowl l()and drying druni 19 and is steamed to give it the proper finish. Thedrying of the fabric and the steainiiigthereof to produce the desiredfinish is effected in succession as the fabric is drawn continuouslyover the drum 53,'shell 10 and steam drum 19. The drying action ismaterially promoted by the described assemblage since the steam pipe 13and to a lesser degree the drain pipe 36 serve to heat the air passingto shell 50 and drum 53.

The numeral 60 indicates a. platform or table on which `fabric A rests.

I would state furthermore that while the illustrated example constitutesa practical embodiment of my invention, I do not limit myself strictlyto the exact details herein il lustiated, since, manifestly, the samecanbe considerably 'varied without departure from y the spirit of theinvention as defined in the surrounding the shell below the upper `endthereof and adapted to permit an outfiow of air to a fabric -diawn overthe drum, and steaming means communicatnig with said pipe and located`for the fabric to be drawn over the saine after drum.

3. In an assemblage of the class described, a drying shell having aninlet for drying air and means on the drying shell over which the fabricmay be drawn, and a drying drum surrounding the shell, said meanspermitting the outflow of air to the fabric passing over the drum. i V

4. In an assemblage of the class described,

passing over the drying air, a collar on said shell, a drum resting onsaid collar, and means detachably holding said drum against displacementon said shell affording an outfiow of air for the drying of lili) thetubular fabric being drawn over the drum.

5. In an assemblage of the class described, steriining means, a steampipe, a perforated shell surrounding said steam pipe and llaving un.inlet for drying air, and a perforated drying drinn on seid shelladapted to receive drying'l nir therefrom, said drum being verticallyadjustable, and means for holding the drum in dierent positions on theshell.
